Data for Data Analysis |

Pages |
ACS Data PROTOTYPE | A small sampler of microdata from the 2013 American Community Survey (ACS). This is another prototype; we're trying to learn how to make this data accessible. |
NHANES Data PROTOTYPE | A small sampler of some of the astonishingly rich data from the National Health And Nutrition Examination Survey. This is only a prototype; we're trying to learn how to make this data accessible. |
Coins | Weights and dimensions of coins from various countries. What's the relationship between diameter and mass? Could it be cubic? |
Hexnuts | Weights and sizes of hexnuts, both metric and English. Data extended from The Model Shop |
Heavy Hexnuts | Weights and sizes of hexnuts, downloaded from a manufacturer. These are "heavy hexnuts," as opposed to the standard ones we're used to. We're using them here because they cover a wider range of sizes. I mean, imagine the 20-pound steel nut that fits a four-inch bolt. Crikey. |
Amortization | If you graph the numbers in an amortization table, what do they look like? Can you model them using functions you know about? |
Shopping Carts | How does the length of a "train" of shopping carts depend on the number of carts? This is a standard problem in math tests; what happens when you go out and measure it? |
The Mettler Scale | You stick some clay on an electronic scale and weigh it. Then you tilt the scale. What happens to the reading? In this case, not what we expected. |
Vegetable Matter | Fruits and vegetables from our local produce market! What's a good way to predict the weight (or mass) of a cantaloupe? Can you use the same scheme on a cucumber? |
Radiosonde | This is height and time data from a weather ballon ascent (same data as in Radiosonde.ftm on the Fathom disk if you have it). How fast does the ballon ascend? How does the speed change? |
Eddy Tube Drop | We time how long it takes magnets to fall through an "eddy tube." We vary the number of pennies we stick between the magnets. What forces are involved? | Pleiades Hyades |
Data about the stars in two famous clusters. Which of the stars in the field are actually members of the cluster? How can you use data to tell? |
Cooling | A beaker of water cools off. We see temperature as a function of time. What is a good function to model the data? |
Heating | A saucepan of water sits on the stove and heats up. We see temperature as a function of time. What is the shape of the data? Qualitatively, is it linear? If not, how can you tell? |
Roller Coasters | Data from 15 roller coasters. We get, among other things, the height of the maximum drop and also the maximum speed. How well does potential energy get converted into kinetic? |
Thin Lenses | Do real lenses obey the thin-lens equation? Here are data from Real Live Students at San Leandro High School (go Pirates!) in California. |
Rolling Friction | We roll a cue ball though a photogate setup and see how the distance it rolls depends on the speed. This also provides an excuse to go to a pool hall on company time... |
Mens 100-m Final, Seoul 1988 | The famous race where Ben Johnson got disqualified. The data include the 10-m splits for the top four finishers. Study speed, acceleration, linear models. |
Slinky Exhibit | |
If you hang a slinky, how does its length depend on the number of coils? |
|
If you hang a slinky, how does the frequency of its oscillation depend on the number of coils? |
|
Does a (horizontal, this time) slinky obey Hooke's Law, F = -kx? How does the spring constant depend on the number of coils in the slinky? |
|
Three Tension Springs | Regular old hardware store springs. We stretch them and measure the force as a function of total length. Do they follow Hooke's Law? |
Electromagnet | A simple electromagnet, nothing fancy. How does its strength depend on current? |
STS-97 Launch | Speed data from a Shuttle launch in 2000. Good for studying acceleration. |
Ramps! A Gravity and Acceleration Exhibit | |
Following Galileo's footsteps, actual students roll carts down ramps to try to determine the acceleration of gravity. Good for simple quadratics, basic trig, and measuring angles in radians. |
|
Tennis
Ball Cue Ball |
We roll a tennis ball, and then a cue ball, down a ramp. This time we measure the speed at the end of the roll. Good for fitting models to data; also, preparing data properly for analysis. |
Ball Time and Distance | Berkeley High students roll a steel ball down a ramp, timing how long it takes the ball to get to the bottom from various heights. Does the ball accelerate uniformly? And how do we deal with variability in the data? |
Hanging Triangles | A statics experiment from a physics lab. An application of trigonometry. Good for studying components of vectors. |
Magnetic Repulsion Exhibit | |
Magnet
Force 1 Magnet Force 2 |
How does the repulsive force between magnets depend on distance? Here we have data taken by students in Millbrae, CA. Good for looking at power-law relationships. |
